Parse Android boot.img.
The Android boot.img contains kernel, ramdisk and optionally second
stage bootloader. Both kernel and ramdisk could be compressed by gzip.
This patch add a new boot img filesystem to parse boot.img to split
it into |File|s, and find the deflates to utilize puffin, which could
save us several MBs in delta payload size.
As a side effect, generating delta payload for boot partition is much
faster because it is now splitted into smaller files, and we can make
use of multithreading.

Test: generate a delta payload
